Abstract: The present invention relates to assisting a user in selecting a lighting device design by providing a lighting device design based on a model or image of a lighting device design (e.g. the user uploading an image of an existing lighting device in his/her home). The lighting device design of the model or image is analyzed in order to determine a lighting device design related variable (e.g. type, shape or color of lighting device design). This variable is then used to select a lighting device design from a set of lighting device designs (e.g. to select a lighting device design of the same color, from an electronic catalogue of lighting device designs); or to generate a lighting device design (e.g. to generate a lighting device design that is a copy of the lighting device design in the image, only smaller and in a different color). The invention further includes a system and computer program product for implementation of this method.
